BEAM Plus Materials Aspects

Principal Aims :

1. Promote Sustainable Use of Natural ResourcesTo use natural, sustainable, rapidly renewable material; to save natural

resources including using recycled content material and reused material to

achieve low environmental impacts, protect ozone layer & minimize

greenhouse gas.

2. Efficiency Use of MaterialsTo re-use of building elements, flexibility in design, off-site fabrication of

major building components, allows for deconstruction, and improves

durability and longevity of buildings.

3. Waste• Minimize waste generation.

• Encourage waste recycling.

• Conserve land filling space.

Over 90% of construction waste are inert substances (惰性物料) and are known as

public fill. Public fill includes debris, rubble, earth and concrete which is suitable for

land reclamation and site formation. When properly sorted, materials such as

concrete and asphalt can be recycled for use in construction.

• Remarks:

• Exclusion: small air-conditioning unit, other equipment such as standard refrigerators,

small water cooler and any other cooling equipment, that containing less than 0.23kg

Ozone Depleting Potential (ODP)

Ozone Depleting Potential (ODP) is the ratio of calculated ozone column change for each

mass unit of a gas emitted into the atmosphere relative to the calculated depletion for the

reference gas CFC 11 (ODP = 1.0). This allows different chemicals to be compared using a

common unit (CFC 11-equivalents). For example, Halon 2402(ODP = 6) is six times more

detrimental to the stratospheric ozone layer than CFC 11.

Source: http://scorecard.goodguide.com/chemical-profiles/def/odp.html

Global warming potential (GWP)

is a relative measure of how much heat a greenhouse gas traps in the atmosphere. It

compares the amount of heat trapped by a certain mass of the gas in question to the amount

of heat trapped by a similar mass of carbon dioxide. A GWP is calculated over a specific

time interval, commonly 20, 100 or 500 years. GWP is expressed as a factor of Carbon

Dioxide ( GWP is standardized to 1).
